Data Binding

I am still learning C# and would like to know what the most efficient means is to bind data from a database into this simple application I have written. I'm still very confused by DataGrids, Data tables, Data Sets, Adapters, etc. I think there's something basic I am not getting.

The application is as follows:

The user enters some parameters X, Y, Z about themselves, and then the application goes to the datbase and finds X, Y, Z (all keys in the table) and returns A, B.  There is only ONE resulting row containing A and B, never more than one row. I need to display A and B on the page in a Label field, so how do I get this result and display it?

What should I use? Seems like overkill to use a Data grid or data table for just one resulting record.

Once I get the result set back, can I bind it to a label field? or does it have to be bound to a repeater (also overkill for this application).

I got as far as the DataAdapter, but I'm not sure what to do from there. Help!

You basically have a few groups of object that go together. A DataSet is a container object that holds one or more DataTables. A DataAdapter acts as an intermediary between between the DataSet and your database. DataReaders are fast, light-weight data objects that give you forward-only access to your data (this would be the most suitable in your scenario).

The DataGrid, Repeater, etc, are UI elements that display data stored in DataTables/DataSet or pulled back with a DataReader.

Labels are dumb, in the sense that the do not directly support databinding in their own right. They can pull data from a data source, but only when they are inside a data-aware control such as a grid or repeater, etc.

So I would probably have to use a repeater even though there's nothing that will repeat?

...and I would bind the repeater to the data reader?

Not necessarily. A DetailsView might suit your purpose because it is designed for displaying a single record at a time:
